Abstract: 1,198,216. Halogenated cobalt-phthalocyanines. FARBENFABRIKEN BAYER A.G. 27 Aug., 1968 [31 Aug., 1967], No. 40879/68. Heading C4P. Novel cobalt-phthalocyanines, optionally substituted in the benzene rings, and containing at least one halogen atom linked to the cobalt atom, are prepared by treatment of an appropriate cobalt-phthalocyanine with a halogen or halogenating agent under conditions such that no noticeable halogenation of the benzene nuclei takes place, and in particular in the absence of a halogenating catalyst, the reaction being effected in an inert dispersing agent free from hydroxyl and amino groups. Suitable halogenating agents are elemental halogens, SCl 2 , S 2 Cl 2 , SOCl 2 , SO 2 Cl 2 , PCl 5  and POCl 3 ; and suitable dispersing agents are CCl 4 , CHCl 3 , nitrobenzene, chlorobenzene, o-dichlorobenzene and trichlorobenzene. Reaction temperatures can vary between 0‹ and 150‹ C. Whether the product contains 1, 2 or 3 Co-bound halogen atoms depends on the duration of the reaction and the nature of the halogen, and when reaction is prolonged nuclear halogenation may also take place. Reduction of the halogenated compounds, which can be used, for example, as dyestuff intermediates, preferably in high boiling inert dispersing agents, e.g. dimethyl aniline, quinoline, with addition of some hydroquinone, gives the halogen-free cobalt-phthalocyanines. Tetraphenyl-cobalt-phthalocyanine is prepared by heating 1-amino-3-imino-5-phenyl-isoindolenine with CoCl 2  in quinoline.

Abstract: 893,701. Making finned tubing; welding by pressure. BUSSE, F. Dec. 10, 1959 [Jan. 13, 1959], No. 41967/59. Classes 83 (2) and 83 (4). In making helically finned tubing, e.g. for heat exchangers in gas-cooled atomic power plants, at least one U-section strip is wound under tension continuously and helically on to a tube and is resistance seam welded to the tube, alternating current of at least one hundred kilocycles per sec. being fed to the strip and tube at points close to and in advance of the welding point via contacts. A U-section strip 1, Fig. 1, is drawn off a roll and wound helically under tension on tube 2 with a contact 4 applied to the bottom face of the U-section and a contact 6 pressed against the tube adjacent the weld point 5. The contacts are supplied with current of preferably 400-500 kc. per sec. The pressure exerted on the strip may be supplemented by a roller 10 of poor heat conductivity which engages the base of the U-section between the limbs thereof and which has two discs, one on each side, to maintain the shape of the U- section and to effect shaping of the base of the strip during welding. In a modification, one or two contacts in parallel are pressed against the outer faces of the limbs of the U-section. In another embodiment, in which the strip and tube are heated to a temperature below welding temperature by the high-frequency alternating current and are additionally heated at the welding point by roller electrodes, at least two U- section strips 20, 21, Fig. 4, are wound side by side on the tube with their bottom faces engaged by high-frequency supply contacts 27, 28 and with the wall of the tube engaged by high-frequency supply contact 29. Electrode rollers 23, 24 are inserted between the limbs of the U-sections.

Abstract: 1,133,091. Coupling arrangements for A.C. networks. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 22 Sept., 1966 [5 Oct., 1965], No. 42219/65. Heading H2H. In an A.C. system comprising power sources 1<SP>1</SP> ,  2<SP>1</SP> ,  loads 15, 16, bus-bars 12, 13, circuitbreakers 7... 10 and a transmission line formed by two parallel feeders 23, 24, a coupling 11 is inserted to prevent the synchronous machines in the sources 11, 2<SP>1</SP> from falling out of step when an earth fault occurs at point 14 and the power flow through line 23, 24 is normally from bus-bar 12 to 13. The coupling 11 is of the type comprising a series inductance and capacitance combination resonant at normal network operation to present a predetermined low impedance and detuned automatically by a predetermined excess current which saturates a reactor connected in series with a resistor across the capacitor, Fig. 1 (not shown). The value of the resistor is chosen so that during fault conditions it imposes on the machine(s) in the source 1<SP>1</SP> an additional power demand to slow the machine(s) down simultaneously with the machine(s) in source 2<SP>1</SP>, the latter effect being due to source 2<SP>1</SP> having to supply during fault conditions a greater than normal proportion of the power required by the load 16. The coupling operation is arranged so that it presents a sufficiently low impedance during the "swing" conditions following fault removal to maintain stability in the system and prevent pole slipping. Couplings may be connected at other points in the system as required and may be of the type wherein the resistor is in series with a spark gap or surge diverter instead of a saturable reactor. Use may be made of various components of the system, e.g. machines, transformers, lines or cables, to contribute towards the inductance and capacitance of the coupling, whose power demand to slow down the machine(s) in source 1<SP>1</SP> may be provided or supplemented by the hysteresis effect in a reactor core.

Abstract: 901,460. Measuring bridges. LONDON ELECTRICAL MANUFACTURING CO. Ltd. Dec. 16, 1960, No. 43341/60. Class 37. A four arm A.C. measuring or test bridge comprises means to disconnect the impedance under test and the normal impedance in a ratio arm, and an adjustable impedance inserted in the ratio arm to rebalance the bridge for the stray impedances of the bridge circuit while the test and normal impedances are disconnected. A capacitance test bridge comprises a test capacitor X connectible by switch 13 across stray capacitances represented by S, a standard capacitance C, and ratio arms comprising resistance T, and a balance resistance R shortcircuitable by switch 15 in series with variable resistance r. Initially, switch 13 is open and switch 15 is closed for resistance r to be adjustable to balance for the stray capacitance S, and thereafter the switches are reversed for the bridge to be balanced for X, and it is shown that X R - = - independently of the stray capacitance. C T A variable capacitance small relatively to X may be connected across S and set to a median value for initial balance, and may thereafter be adjusted to introduce additive tolerances to the value of X for which the bridge is balanced. For production testing capacitors, two bridges may be used set for high and low limits of X, with automatic indication of the kind set forth in Specification 899,024. Series inductance may be inserted for balancing series or isolating stray capacitances. In a modification (Fig. 2), the bridge comprises a standard resistance R, a test resistance W in parallel with stray or leakage resistance U and ratio arms comprising resistance S and variable resistance T in parallel with a resistance V. Initially W and V are switched out and the bridge balanced, after which it is rebalanced with W and V inserted and it is then R S shown that - = - independently of the stray W V resistance.
